The latter of said patents-na mely, No.653,337discloses a very simple and effective type of bale-band fastener,essentially consisting of a rotatable buckle. So for illustrativepurposes, to show the action and function of the tool, this type offastenerisindicatedin the drawings. The said fastener essentiallycomprises a flat buckleplate A, adapted to turn bodily upon one edge asafulcrum and provided with a band-receiving eye or opening B,whichreceives the lapped ends of the bale-band 0, said plate being furtherprovided with a pair of holding-arm extensions D,having terminal hooksE. These terminal hooks E of the buckle-plate 1 cooperate with alocking-key F, adapted to be passed transversely beneath the band afterthe plate has been turned bodily upon itself and the hooks E thereofforced beneath the plane of the inner side of the band. This generalform of bale-hand fastening can be manipulated with great facility bythe turning-tool forming the subject-matter of the present application,and particular reference will now be made to this tool.

The tool as an entirety is in the form of a lever carrying suitableelements or members providing for the bodily turning of the flatbuckle-plate or winding element A of the fastener, and this lever, whichis designated by the reference-nu meral l, essentially comprises astraight handle portion 2 and a carryingyoke 3, which provides a supportfor the op erative members of the tool having direct cooperativeengagement with the buckle-plate or winding element of the fastener. Thestraight handle portion 2 of the lever is preferably of a hollow ortubular construction, for the purpose hereinafter explained, and ispreferably provided at one end with a loop 4, which affords convenientmeans whereby the tool may be suspended from a suitable hanger, ifdesired. From a structural standpoint it is of course unimportant howthe lever 1 is constructed-whether integrally or of separate parts--buta preferable construction is shown in the drawings and resides in havingthe carrying-yoke of a separate piece and provided at the closed side orend thereof with a collar 5, within which is received and rigidlyfastened the end of the handle 2, opposite the hanger-loop 4. Thecarrying-yoke 3 of the lever is preferably of a U form, so that the samewill stride the buckle-plate or winding element A of the fastener toprovide for the proper positioning of the oppositelyarrangedturningheads 6, which are supported by and carried with the yoke 3. Thesaid turning-heads 6 are arranged in diametrically opposite relation andin transverse alinement, the same being respectively located at theinnersides of the opposite side arms 3 of the carrying-yoke 3 andcontiguous to the terminals or extremities of said side arms, as plainlyshown in Fig. l of the drawings. The diametrically opposite relation andtransverse alinement of the pair of turning-heads 6 provides for sucharrangement of these heads as will permit of the same being engaged withopposite side edges of the rotatable buckle-plate or winding element ofthe fastener, and thus insure the distributing of the leverage orturning strain uniformly throughout thesaid plate or winding element.

The precise configuration and form of the turning-heads 6 may bematerially varied in the practical carrying out of the invention, as itis only necessary that eachof said heads be provided with means wherebythe same may be detachably interlocked with the huekle-plate or windingelement of the fastener. A simple mechanical expedient for providingthis connection resides in constructing each of the turning-heads 6 witha transverse engaging slot or groove 7, extending transversely acrossthe inner face thereof and of a sufficient width to receive therein theedge of the buckle-plate or winding element.

Each of the turning-heads 6 is designed to be positively rotated byaswinging movement of the lever 1 to insure the bodily turning of thebuckle-plate or winding element. To secure this result, it is necessaryto rotatably support the heads 6 and provide means for imparting apositive rotation thereto. The preferred construction is shown in thedrawings and involves forming each turning-head 6 with a bearing-hub 8,projecting from the outer side thereof and loosely journaled in abearing collar or opening 9, formed in the terminal or end portion ofthe adjacent side arm 3 of the carrying-yoke, and to prevent displacement of the bearing-hub of each turning-head from the bearingtherefor there is employed a retaining or pivot bolt 10, passing throughthe bolt-opening 11, formed in the turning-head 6 and its hub, andreceiving upon the outer threaded extremity thereof thebinding-nut 12,which binding-nut also serves to hold in place the resetting-cam 13,which constitutes a member of the complete resetting device hereinaftermore fully described. It may be observed, however, at this point thatthe resetting-cam 13, asso ciated with each turning-head, also acts inthe capacity of aguardplate,cooperating with the bolt 10 to preventdisplacement of the turning-head from its hub, and inasmuch as in theoperation of the tool it is necessary for the resetting-cam for eachhead to turn with the head an interlocking connection between theseparts must be provided. The preferred form of interlocking connectionconsists of a retaining pin or stud l4, projecting from the outer sideof the bearing-hub of each turning-head and detachably engaging in anopening 15, formed in the cam 13, fitting against said outer side of thebearing-hub upon the outer side of the side arm 3 receiving the same.

To provide for propelling or actuating the turning heads, thebearing-hubs 8 thereof,

working within the bearing collars or openings 9 of the yoke, areprovided with a circumferential or peripheral series of ratchet teeth ornotches 16, with which codperate the beveled points 17 of pivotal actuating-pawls 18, seated within pawl-recesses 19, formed in the outerfaces of the yoke side arms 3 and pivotally mounted at one end uponpivotbolts 20, passing transversely through the said side arms, asplainly shown in the drawings. The points 17 of the pawls 18 are normally and yieldingly held in operative relation to the ratchet-facedhubs 8 of the turninglieads by means of coil-springs 21, arranged in thepawl-recesses 19 and bearing at one end against one side of the pawlsand at their other ends against the tension -screws 22, mounted inthreaded openings in the edges of the yoke-arms 3" and serving toregulate the tension of the springs 21, while at the same timefacilitating the removal and replacing thereof. The pawls 18, which arerespectively arranged in the recesses of the opposite yoke-arms 3, areproperly retained within their recesses by the cover or guard plates 23,fitted upon the outer sides of the arms 3 over the pawl-recesses 19 andalso receiving the bolt. 20, which constitute the pivots for the pawls.

Each of the turning-heads has fitted thereto in the manner explained aresetting-cam 13, and each of said cams is preferably of an approximateU shape and is adapted to normally register within a correspondingcomplementary approximately U shaped bearingfork 24:, formed at theupper extremity of one of the side slide members 25 of the holdingclutch26. Each slide member 25 of the holding-clutch 26 is also providedcontiguous to the terminal bearing 24: thereof with alongitudinally-disposed guiding-slot 27, which slidably receives theouter extremity of the adjacent pivot-bolt 20, which therefore serves topositively guide the clutch in its sliding or reciprocatory movement.The holding-clutch 26,which,with the pair of cams 13, constitutes a complete resetting device for the tool,is preferably in the form of aUshaped frame conforming substantially to the exterior contour of theU-shaped earrying-yoke 3 of the lever, so that the slide members 25 ofthe clutch or clutch-frame will be arranged upon the outer sides of theyoke lever-arms 3 and will have a sliding movement with referencethereto. The slide members 25 of the clutch coiistitute the sideportionsof the complete clutch-frame, and they are joined rigidly with asleeve 28 at the closed end of the clutch-frame, said sleeve slidablyfitting upon the straighthandle 2 of the lever contiguous to theconnection of the lever-handle with the carrying-yoke and receiving-atransverse guide-pin 29, working through a longitudinally-disposedguiding-slot 30, formed in the lever-handle 2, and having exertedthereagainst the pressure of the pressurespring 31, housed Within thetubular levenhandle 2. The pressure of the spring 31 is normally exertedin a direction to move the clutch-frame outward upon the carrying-yokeof the lever, and thus normally hold the terminal hearingforks of theclutchframe in registered interlocking engagement with the resetting-cams for the turning-heads, thus holding the said turning'heads innormal positions for being slipped upon the huekle-plate or windingelement A of the baleband fastener.

In using the tool it simply necessary to bring the engaging slots of thegrooves '7 of the turning-heads into register with the opposite sideedges of the buckle-plate or wind ing element A and then to slide saidturning-heads upon the said plate or element to an intermediate positionthereon. Then by a slight back-and-forth swinging movement of thelever-handle the actnating-pawls 18 will be worked over theratchet-faced hubs 8 of the turning-heads, thus causing said heads torotate upon their axes a nd serving to bodily turn the buckle-plate orwinding element of the fastener. This motion is continued until thebuckle-plate or winding element has been completely turned and thelockingkey inserted in place to secure the fastener, after which theturning-heads may he slid off of the buckle-plate.

In connection with the resetting device, consisting of the clutclrfralneand the rotatable cams 13, it should be observed that as theturning-heads 6 are rotated the cams 13, which work therewith, are alsoturned and caused to have their side portions bear upon the sides of theterminal bearing-forks 24 of the clutchframe, thus causing this frame tobe pressed outward toward the swinging end of the lever and against thetension of the pressurespring 31. In this action of the cams 13 theU-shaped portions thereof turn entirely out of the forks 24-; butimmediately upon disengaging the turningheads from the buckleplate orwinding element the spring 31 comes into action and forces theclutch-frame 26 in a direction toward the turning-heads, thus causingthe terminal bearing-forks 24E to bear against the cams 13 and turn thesame back upon their axes and into position for receiving thereover thecomplete forks 24, thereby returning all parts of the tool to normalpositions, as will be readily understood from the foregoing description.

From the foregoing it is thought that the construction,operation,andmany advantages of the herein-described turning-tool will be readilyapparent to those skilled in the art without further description, and itwill he understood that various changes in the form, proportion, andminor details of construction may be resorted to without departing fromthe principle or sacrificing any of the advantages of this invention.
